Hi,
i installed Linux(32Bit) in a virtual mashine. Then installed scilab
from command line. Following folder struckture comes out:
/usr/lib/scillab
/usr/include/scilab
/usr/share/scilab
then i created a short c file test.c :
#include "stack-c.h"
#include "call_scilab.h" /* Provide functions to call Scilab engine */
int main(void)
{
if ( StartScilab(getenv("SCI"),NULL,NULL) == FALSE ) {
fprintf(stderr,"Error while calling StartScilab\n"); return -1;
}
SendScilabJob("myMatrix=['sample','for the help']"); return 0;
}
Set up:
export LD_LIBRARY_PATH=/usr/lib/scilab:$LD_LIBRARY_PATH
export SCI=/usr/share/scilab
Start:
gcc -o myExample -lscilab -L/usr/lib/scilab -I/usr/include/scilab test.c
(alternative see makefile )
*Error:*
gcc -o myExample -lscilab -L/usr/lib/scilab -I/usr/include/scilab test.c
test.c: In function \u2018main\u2019:

-- tested on different Linux systems and with the Download version
scilab-5.5.0
has anyone tested this?
